Queen Himiko is the ruler of Sei-an City with the largest palace in the aristocratic quarters. The Emperor and Queen Himiko never acknowledge one another’s existence and Himiko seems to be the one in charge of Sei-an City while the Emperor acts merely as a decoration. Initially she seems to care little for her people after holing herself up in her palace when a sickening mist engulfs the city crippling its citizens. Aware of evil forces far more vile than the mist she locked herself away to offer prayers and focus her holy energy to locate Oni Island which was the source of the evil beings that plagued the area.
Queen Himiko enlisted the help of Ōkami Amaterasu who cleared the mist and devised a way to reach and break Oni Islands barrier. Meanwhile Himiko was located, slain, and devoured by a kitsune named Ninetails. However Himiko had predicted that ninetails the lord of Oni Island would come for her and had entered the crystal ball she used to focus her holy energy. After being devoured she was able to locate Oni Island and pass along it’s location to Amaterasu. This feat required so much energy and greatly tampered with the crystal ball’s power that soon after it split and shattered with Himiko’s soul intertwined with every shard.
